Distribution

The succulent is found growing in the Palos Verdes Hills on the Palos Verdes Peninsula coast in Los Angeles County; on several of the Channel Islands in California; and on Guadalupe Island off the northwestern Baja California Peninsula, Mexico.

Description

Dudleya virens leaves are fleshy and strap-shaped, 8–20 cm long and 1.5–3 cm broad, tapering from the base (or from near middle) and are mostly green. They are arranged in a rosette.

The flowers are white, with five petals 7–10 mm long; they are produced in April, May, and June. Hummingbirds visit the flowers for their nectar.

Subspecies

Subspecies include:

  • Dudleya virens subsp extima — endemic to Guadalupe Island, Baja California.[3]
  • Dudleya virens subsp. hassei — endemic to Catalina Island, California.[4]
  • Dudleya virens subsp. insularis — Catalina Island, San Nicolas Island, Palos Verdes Hills; endemic to California.[5]
  • Dudleya virens subsp. virens — Catalina Island, San Clemente Island, Palos Verdes Hills; endemic to California.[6]

Cultivation

Dudleya virens is cultivated as an ornamental plant in the specialty native plants and succulents horticulture trade.[7] It is used in containers, drought tolerant landscapes, and habitat gardens. It prefers well-draining soil, and grows best in full sun or light shade.

gollark: Yes, it's not really a *significant* issue compared to the bigger ones of spreading disease, but it is there.
gollark: Apparently quite a lot of that runs over side channels like facial expression rather than actual words.
gollark: > How are masks dehumanizing?They somewhat worsen communication, I guess?
gollark: Possibly. It seems unlikely that they would say it if it wasn't somewhat necessary, it makes it significantly less attractive.
